Be it known that I, JosrrH BRANDWOOD, a subject of the King of Great Britain, residingat Newton, in thecounty 0f- Midi dlesex and State of Massachusetts, havegmthe 'rod 'sov that the rod rotates; and each invented certain new and useful Im filevements in Apparatus for the Contixuous .to trave about in lits own position by each part. of it l.passing up to, over and ,down from the "rod, above which may be the spra .of treating fluid. This is old,` '-butto a Vance the rodssidewise from time to time,.as is necessary for their progression through' the zone,it has been proposed to have a-rail running under all of the rod ends at each side,and periodically to lift them-all by these rails and ltransplant them of which lthe following is a specification.

This invention relates to improvements in apparatus for the continuous treatment ofl textile fibers in skein form. y More particularly it relates -to apparatus for subjecting material, which may for example be in the form' of skeins orhanks, to the action of, any desired' fluid, as by spraying a liquid about in its position, so that various parts ofit are subjected to the action of the' fluid, and also advancing the skein through the zone of action of the fluid, or through the lifting effort periodically with. strong rails to support lall off the yarn j and all of the rods atonce; and as the supporting andy gangs rotating oppositely, it also involves and'thence out from the apparatus. vThus itprovides for exposing each skein thoroughly for a predetermined time to treatment by each successive fluid.

The invention is concerned'with apparainactive, while it is positioned between the arrangement also entails the vdisadvantage that the rotation of yarn in either particutinued before the reversal occurs.l The improvement provides for making the reversals at short intervals; eliminates the inactive position between the two directions with the particular materialstreated, or which constitute the treating substances. Therefore,'in general the `material treated may be of any sort, such as cotton, wool, silk or artificial fiber; the fluid may be applied in any manner; and in the case of for lifting all of the materials andi rods at application by spraying may be applied exonce, together with theapparatus for lifting to the 'skein';"and the purpose of the treatment-may be for the ordinary textile operations of bleaching? dyeing or washing, or for other chemical treatments such as are suitable for dealingjvith cellulose. Likewise, the fluid is 'not necessarily a liquid, but by .jets of air or some otherl gas, the apparatus can be used fordrying, or oxidizing, or subjecting the material Aotherwise to each rod' is advanced by being rolled` sidewise over itssupport, thus taking it one step through the apparatus with a minimum exertion which -is subdivided and distributed at the places where the work is done, and

being applied to the whole machine by extremely simple apparatus located at one end thereof.` Y

1t has already been proposed to hanga These aims 'are accomplished by providsuccession of skeins side-by side upon a ing a pawl at each rod-end position which single rod, and then ,to -move a succession at the p roper time simply pushes that rodof such rods sidewise through aonesgwhere end in the direction in which it is to adthe skeins thereon aretreated` Theinvenvance, and then returns to tion providesimproved means for this, with pushing the `next, rod throng the, same more perfect operation, greater capacity of step.

yielding' rotation of the finger in the opposite direction to .pass under the rod next to the rear when the bar and its pivot are drawn backward. The bars are reciprocated endwise at proper times by a simple cam movement.

For the reversal of rotation,

all supporting rollers are simultaneously reversed in their drive by a clutch mechanism, atintervals whichcan'be predetermined as shortv them 434, has

as may be thought wise.

The invention may be applied to various mechanisms, that chosen for illustration being one in which the fluid applied is a liquid sprayed on the top of the skeins as they pass over their rods. However, the spray o'r outflow of fluid might be otherwise applied; and variations may be made in other particulars from the specific ap- It is intended thatthe patent shall cover by suitable expression in the appended claims whatever features of patentable novelty exist in the invention disclosed.

Referring to the drawings, the skeins which are being treated are marked 10 and comprising a. body pivoted on. the

A long series of these rods is arranged extending from right to left in Figure 1, Awith individual rods 1 (5 seen in Figure 2 positioned side by side and laden as indicatedin Figure l, eachend of each rod resting on and in the Valley between a pair of rotating rollers or friction drive wheels 20. These may be rotated at a slow and regular means. The device shownis that each roller is on a. shaft 24 whose gear 28 is turned slowly by one of a series of worms 26.dis tributed along shafts 30, 30', `one of which rate by any suitable- Gearing 32 connects the shaft 30 at'v the left in Figure 2, with the shaft 30at` the' right in Figure 2,'which latter has direct drive at the power end of the machine seen at the rear and right in Figure 1. At this end there are oppositely rotating drive pulleys 34, 36, which by clutch 38 may be placed in engagement with the shaft 30 to make it rotate in either direction, both pulleys 34 and 36 being loose on shaft 30. But one of p its hub connected by gearing l40 with shaft 42 on which is a worm that drives gear 44 and its shaft 46 which runs across the machine near the bottom and has.

identical cams 48, oneat each side of the machine, foreffecting the step by step advancement of the skein rods, and has a single cam 50 operating through roller 52 and lever 54 to move the clutch gage the shaft 30 either with or reverse drive pulley 36 or from both for a brief pause. rod rotating rolls 20 are driven by direct connection from the power 34, 3G, in either direction, with a pause at reversal, while the reversing mechanism itfor advancing the drive pulley 34 to disengage it lar rate in the same direction. y

By the cam 50 reversal of the rotation of the skein carrying rod 16 can be predetermined to be as often as desired,- and rotation may continue for as many revolutionsy in each direction as desired (by virtue of the differential time element which can be introduced through the train of gearing 40), as compared with the number of rotations occuring meanwhile ofthe rod.
